IMPROVE M ENT IN l-IARVESTE'R RAK ES.

To all whom itmcy concern 7 Be it known that I, HENRY W. DETERL DING, of Alton, in the county of Madison-and State of Illinois, have invented anew and Im- 1 proved Raking Device for Harvesters; and that the following description, taken in con nection with the accompanying drawings, here- 9 inafterreferred to, forms afull andexact specification of the same, wherein I have set-forth the nature andprinciples of my said improve- Inents, by which my invention may be distinguished from-all others of a similar class, together with such partsas I claim and desire i. to have secured to me by Letters Patent.

This invention relates to anew and improved 5 device for raking automatically the out grain from the platforms of harvesters; and it consists in-a peculiar construction and arrangement of parts, as hereinafter fully shown and described, wherebythe desiredwork may be performedin a perfect manner.

In the accompanying sheet of drawings, Figure 1 is a rear viewof a harvester provided with my invention; Fig; 2, a plan or-top view of the same; Fig. 3, a detached-plan or top view of the rake pertaining to the same.

Similar letters of reference indicate like parts. r

A represents the main frame of theharvester, which is mounted on two wheels, B B, and is provided with the usual draft-pole G. The wheels B B are firmly keyed on their axle D, so that the latter turns with the former; and on the axle there is firmly keyed a small bevel-pinion, E, which gears into a corresponding pin ion, F, placed loosely on. the inner end of a.

sition on the framing, and a clutch, H, upon it, whereby the pinion F may be connected with shaft Gr when desired, and motion communicated to the latter from the axle.

I ()n the outer end of the shaft G there is firmly secured a wheel, I, which has a series of holes, a, made in it at different distances from its center, as shown inFig. 1. Inany one of these holes a screw-bolt, 1), passes, which secures a rack-bar, J, to the wheel I, and this rack-bar gears into a pinion, c, which is attached to a toothed wheel, K, said pinion and toothed wheel being placed loosely on a fixed axis, 07. This rack-bar works in a guide, L, which is fitted loosely on the axis cl, and has a roller, e,attached, which bears upon the upper surface of I the rack-bar, andkeeps the latter in gear with the pinion c. ThewheelK gears'into a pinion, L, on the outer-or rear end of ashaft, M, which has its bearing f atthe right-hand side of the rear end of the main frame. This shaft M is connected, by a universal joint, N, with a shaft, 0, the front end of which is connected by a similar joint, P, with asmall= shaft, Q, which is fitted in one end of a metallic framing, Q, attached to the frontof the platform S, and projecting beyond its left and right hand sides.

-On theshaft Qthere is a toothed wheel, T,

- g and a-simi1ar wheel, U, is placed on a small shaft in the "right hand side of the metallic framing- Around these two wheels T U an endless chain, V, passes, which has its motion communicated toit. fromthe wheels D B of themaehine through themedium of the gearing abovedescribed and this movement of thechain is not a continuous one inthe same direction, but a-reciprocating one,first in one direction andthen in the othera result due to the ia'ck-barJ and itsconnection to the wheel I and the gearing c K L, by which the shaft The sickle is at the front of the platform, asusual,-and may be operated in the ordinary or,

in any proper manner. v

The platform S is slotted in a direction par allel with the front edge, to admit of raketeeth h passingup through it and traveling itsfwhole length, or from its right to its left hand side. These --'rake-teeth are attached to a shaft or rod, 6, one end of which is fitted and allowed to turn freely in a socket, W, which is secured to the chain V. The shaft or rod i has a spiral spring, j, wound around it, and this spring has a tendency to keep the raketeeth h in a vertical position, so that they will extend up through the slots in the platform.

The outer tooth h of the rake is curved or bent, as shown at k in Fig. 3, and the upper plate of the framing Q has a slight elevation, l, underneath which there is a plate, Y, pivoted, as shown at m, and this pivoted plate has a spring, n, bearing against it, which has a tendency to keep the edge of plate X across I the front slot in the platform, as shown clearly edge of the same plate of the framing, and

near the outer side of the platform, there is made a recess,- 0, which is also shown clearly in Fig. 2.

Y is a divider, which is attached to the outer side of the platform, and supported by wires or" rods p, which prevent the grain from passing underneath it, but admit the rake-teeth h to pass under and out from underneath the same.

The operation of the rake is as follows: (It will, of course, be understood that the rake has a reciprocating motion, as the chain V has that motion communicated to it, as previously described:) When the rake-teeth, h, move in the direction indicated by arrow 1, the teeth project up through the slots in the platform S,

and rake the cut grain therefrom, discharging it between the inner end'of the platform and the main frame. c

When the teeth It nearly reach "the termination of their working movement, the outermost or front tooth h" of the rake comes in contact with the pivoted plate X and forces it back and passes it, so that as the teeth h'commence their return movement in the direction indicated by arrow 2,the plate X, which springs back across the front slot in the platform as soon as the tooth h" passes it, serves as an obstruction to the return movement of the rake- .teeth, and causes the rake-teeth to be turned down, the bent end kof the front or outermost tooth h passing through a recess, q, in the inner edge of the plate of the framing Q, and

I the bent end h" of the tooth h passes underneath said plate, and all the rake-teeth are kept down, so as not to interfere with the fallingof thecut grain on the platform until-the rake reaches the termination of the movement in the direction of arrow 2, at which time the rake-teeth will be underneath the track-clearer Y, and the front or outermost rake-tooth h will be in line with the recess 0, which admits of the spring j throwing up the rake-teeth to a vertical position, so that they will rake the cut grain from the platform as they commence to move in the direction indicated by arrow 1. Thus; by this simple means, the cut grain may be raked automatically from the platform, and without any special care or attention on the part of the driver.

Having thus described my invention, I claimas new and desire to secure by Letters Patent 1. The wheel I, rack J, gearing'c K L, and the shafts M O Q, all arranged and applied as shown, or in anequivalent way, for thepurpose of operating the endless chain V and rake, substantially in the manner as and for the purpose set forth.

2. The pivoted plate X and spring n, in connection with the recesses o q in the inneredge of the plate of the metallic framingQ, and the bent rake-tooth h of the rising and falling rake, all arranged to operate with the slotted platform S, substantiallyas and for the purpose specified. 3. The coiled spring j, in combinationwith the rake-head i and socket W, whereby the rake-teeth h are held in a vertical position, as herein described, for the purpose specified.
